1 mole each of ${\mathrm{SO}}_2$, ${\mathrm{NO}}_2$, ${\mathrm{SO}}_3$ and NO is taken in a container of one litre capacity when the following reaction takes place:

${\mathrm{SO}}_2(g)+{\mathrm{NO}}_2(g)\rightleftharpoons {\mathrm{SO}}_3(g)+\mathrm{NO}(g)$

At a certain temperature, the value of $K_c$ is 16. The $[{\mathrm{SO}}_3{]}_{eq}$ is:
